Solar energy installations are sprouting up all over Vermont—especially photovoltaic systems that convert sunlight energy directly into electricity. In this talk Middlebury College Professor of Physics Richard Wolfson will give some background on the historical development and deployment of solar energy and then focus on the present-day boom in solar photovoltaics, especially in Vermont. Wolfson will also give a brief description of how these remarkable devices work, and take a look at the future of photovoltaic and other solar energy systems.
